Debug output in QualifierCheck.java

[thallinger]

There is an annoying debug output in QualifierCheck.java that clutters the screen:

58:   String qualifierName = qualifier.getName();
59:   if (qualifierName.equalsIgnoreCase("old_locus_tag")) {
60:     System.out.println(qualifierName);
61:   }

As it seems to have no real purpose, it would be helpful if it is removed in one of the next releases of the library.
